Question : 21 [SSC MTS 2013]
Two trains 108 m and 112 m in length are running towards each other on the parallel lines at a speed of 45 km/hr and 54 km/ hr respectively. To cross each other after they meet, it will take
a) 9 sec
b) 8 sec
c) 10 sec
d) 12 sec
Answer »Answer: (b)
Using Rule 3,
Relative speed
= 45 + 54 = 99 kmph
= $(99 × 5/18)$ m/sec. or $55/2$ m/sec.
Required time = ${108 + 112}/{55/2}$
= ${220 × 2}/55 = 8$ seconds
Question : 22 [SSC CHSL 2010]
Two trains of length 137 metre and 163 metre are running with speed of 42 km/hr and 48 km/hr respectively towards each other on parallel tracks. In how many seconds will they cross each other?
a) 24 sec
b) 12 sec
c) 10 sec
d) 30 sec
Answer »Answer: (b)
Using Rule 3,
Relative speed
= 42 + 48 = 90 kmph
= $({90 × 5}/18)$ m/s = 25 m/s
Sum of the length of both trains
= 137 + 163 = 300 metres
Required time = $300/25$ = 12 seconds
Question : 23 [SSC GL Tier-I 2013]
A train, 150m long, passes a pole in 15 seconds and another train of the same length travelling in the opposite direction in 12 seconds. The speed of the second train is
a) 48 km/hr
b) 52 km/hr
c) 54 km/hr
d) 45 km/hr
Answer »Answer: (c)
Using Rule 3,
Let the speed of the second train be x m/s
Speed of first train
= $150/15$ = 10 m/sec
Relative speed of trains
= (x + 10) m/s
Total distance covered
= 150 + 150 = 300 metre
Time taken = $300/{x + 10}$
$300/{x + 10}$ = 12
12x + 120 = 300
12x = 300 - 120 = 180
x = $180/12$ = 15 m/s
= ${15 × 18}/5$ or 54 kmph.
Question : 24 [SSC CGL Tier-II 2015]
Two places P and Q are 162 km apart. A train leaves P for Q and simultaneously another train leaves Q for P. They meet at the end of 6 hours. If the former train travels 8 km/hour faster than the other, then speed of train from Q is
a) 10$5/6$ km/hour
b) 9$1/2$ km/hour
c) 8$1/2$ km/hour
d) 12$5/6$ km/hour
Answer »Answer: (b)
Speed of train starting from Q = x kmph
Speed of train starting from P = (x + 8) kmph
According to the question,
PR + RQ = PQ
(x + 8) × 6 + x × 6 = 162
[Distance = Speed × Time]
6x + 48 + 6x = 162
12x = 162 - 48 = 114
x = $114/12 = 19/2 = 9{1}/2$ kmph
Question : 25 [SSC CPO S.I.2009]
Two towns A and B are 500 km. apart. A train starts at 8 AM from A towards B at a speed of 70 km/ hr. At 10 AM, another train starts from B towards A at a speed of 110 km/hr. When will the two trains meet ?
a) 12 Noon
b) 12.30 PM
c) 1.30 PM
d) 1 PM
Answer »Answer: (a)
Let two trains meet after t hours when the train from town A leaves at 8 AM.
Distance covered in t hours at 70 kmph
+ Distance covered in (t - 2) hours at 110 kmph = 500km
70t + 110 (t - 2) = 500
70t + 110t - 220 = 500
180 t = 500 + 220 = 720
t = $720/180$ = 4 hours
Hence, the trains will meet at 12 noon.
